Synthesize target molecules, multicomponent reaction of 4-(4-aminophenyl) morpholin-3-one with various pyrazole aldehydes and ethylacetoacetate or methylacetoacetate afforded various 1,4-dihydropyridines derivatives. The newly synthesized compounds were characterized by IR, Mass, 1H NMR, 13C NMR spectroscopy and elemental analysis.
